Will be remaking my Anemo Archon books with Rex having Dvalin as a pet and is an estranged cousin of Reinhardt and Reve.

Involves: 

Half-blind Rex wears an eye patch or covers both his eyes if he wants

Rex and Dvalin share a brain cell

A.A. Rex: No one will notice if- *launches several invisible wind lances at the enemy* there is no one *hic* to notice. *Passes out while floating in the air while several alcohol bottles sound and danced around him.*

Y/N: And I thought Morax was terrifying. 

Zhongli: That damned bard... to think that he would find someone he is so compatible with...
